As for the first error, DINA Merrill is crosswordese (31A: Actress Merrill), and DINO isn't a plausible actress's name, but the TORTE for TARTE error is completely understandable to me (27D: Pâtisserie offering).

Boston Globe: 'It's knowledge of crosswordese that separates the hard-core puzzlers from the dilettantes. You may never, ever find an opportunity to bring Enyo (a Greek war goddess) into conversation, and, like those contestants, you may have never seen an etui before, but if it helps you fill in that last blank square of a puzzle, it will be burned into your brain forever.'
